N2 - Deep tillage tools are one of the primary components of agricultural equipment which experience high level soil reaction forces during tillage operations. These forces may cause plastic deformation or failure which is undesirable for tillage machines/tools. In particular, fasteners such as bolt connections, which are utilised in the fastening of structural elements to the tillage tool’s framework, may become a key point for possible machine failure during tillage operations.
